Syntax:bool Imagick::setResolution (float $x_resolution, float $y_resolution)
Parameters:This function takes two parameters as above and described below: - $x_resolution: specifies the horizontal resolution.
- $y_resolution:specifies the vertical resolution.
Return value: this function returns TRUE on success.Exceptions:this function throws an ImagickException on error.The following programs illustrate the Imagick::setResolution function()in PHP:Program 1:
// Create a new imagick object $imagick = new Imagick();
// Set permission $imagick -> setResolution (18, 13);
// Create new image $imagick -> newimage (100, 100, ’none’ );
// Read image properties print ( "" . print_r ( $imagick -> identifyImage(), true). "
